IPC: C03B7/10
Filed: 1923-07-09
Abstract: 219,165. Dicker, S. G. S., (Owens Bottle Co.). July 9, 1923. Delivering molten metal.-A device for feeding charges of molten glass comprises a receptacle supplied with glass from a furnace and having a discharge aperture in the bottom, a regulator or plug depending into the receptacle over the opening and means for continuously rotating the plug, and also the receptacle, to cause the glass in the receptacle to move around the axis of the discharge opening and relatively to the point at which the glass flows into the receptacle. In the construction shown in section in Fig. 1, metal flows from a tank 21 into a bowl-shaped receptacle 24 which has an outlet 25 and is supported on a circular track 30 by rollers 29. The receptacle is rotated about a vertical axis by means of bevel gears 37, 38 and a. driving-shaft 35. The discharge of metal through the outlet 25 is controlled by a plug 42 which is reciprocated vertically by a cam mechanism and is rotated, preferably at the same angular speed as the receptacle, by means of gearing connected with the driving shaft 35. The charges of metal are severed by shear blades 69 mounted below the aperture 25 and operated periodically in synchronism with the plug. The shear blades are opened and closed by a rocking-arm 78 which is actuated by stationary cams 79, 80. The rotation of the receptacle cause an even distributions of metal around the plug and secures an even distribution of temperature in the column of metal discharged from the orifice. In a modification, the plug is formed with an axial bore which terminates at the lower end of the plug in a cup-like cavity. The bore is periodically connected to a source of partial vacuum which serves to retard the flow of metal through the orifice 25 at about the timethe shearing-device operates. In another form of this construction, the plug is not reciprocated but the axial bore is alternately connected with a source of partial vacuum and with an air pressure supply. The suction retards the flow of metal through the outlet 25 and the air pressure assists in expelling the metal and forming a gob of suitable form.

Abstract: 1,263,466. Luminescent screens. E.M.I. Ltd. 14 March, 1969 [17 April, 1968], No. 18062/68. Heading H1D. [Also in Division C4] A method of providing an adherent coating of phosphor particles on a surface for an image intensifier or cathode ray tube comprises applying a tacky coating then the particles, at least partially removing the coating and providing a protective coating for the particles of polymerized polyvinyl alcohol. A C.R.T. screen is prepared by pouring a binder comprising nitrocellulose powder dissolved in iso-amyl acetate and methyl acetate or an acrylic resin solution with di-n-butyl phthalate plasticizer on to a glass disc rotated to obtain a uniform coating. The disc is heated at 70‹ C. then when cool and the binder tacky ZnS:Ag phosphor particles are rubbed or brushed into the binder. The disc is reheated to 220‹ C. to remove some of the binder including all of the plasticizer. The protective coating is applied by immersing the disc in an aqueous solution of PVA and K dichromate and irradiating the disc with U.V. light to harden the PVA. The remaining binder is removed by baking at 410‹ C. then an Al layer is deposited. A mica sheet for an image intensifier mounted in a metal ring and supported by a rubber sheet fitting within the ring is coated using the previous method except that before the final bake it is soaked in K silicate. Several coatings of different phosphors may be deposited on flat or curved surfaces. Additional fine particles may be applied to fill spaces between larger particles.

Abstract: 257,241. Loveday, W. H. N. Aug. 20, 1925, [Convention date]. Direct air pressure apparatus, automatic ; vacuum apparatus; raising by stages ; valves, actuation and arrangement of. - Apparatus for raising liquids from deep wells &c. comprises two series of chambers 1, 2 so arranged that the chambers of one series alternate vertically with those of the other series, each series being alternately placed under relatively high and low pressures, such as atmosphere and vacuum, by means which are automatically reversed by the rise and fall of liquid in a control chamber. The lowest chamber of one series is connected to the, liquid 5 by a pipe 4 with a non-return valve 6, and each chamber in one series is connected to the chamber next above it in the other series by a pipe 7 provided with a non-return valve. The chambers 1 are connected at the top to a common pipe 10 communicating by a pipe 35 with a port 27 controlled by a slide valve 11; and the chambers 2 are connected to a common pipe 12 communicating by a pipe 34 with a port 30 controlled by a valve 13. The valves are actuated by a float 15 in one of the chambers 1 through a linkworh 16, 22, 17 and a sliding rod 14, which engages slots 19 in the valves and carries pins 18, 18a in the path of the link 17. The movement of the valves is accelerated by a spring lever 20. When the chambers 1 are empty and the chambers 2 full, the valve 11 is in position to connect the chambers 1 to a source of relatively high pressure, such as atmosphere, through pipes 35, 36, while the valve 13 connects the chambers 2 to a source of relatively high pressure, such as atmosphere through pipes 34, 33. Liquid then flows up from the chambers 2 through pipes 7 to the chambers 1 until the float 15 rises and reverses the valves 11, 13, causing the chambers 2 to fill and the chambers 1 to discharge. A float-controlled valve 8 in each chamber controls the liquid outlet and prevents the chamber from completely emptying. The pipes 7, 10, 12 may be arranged inside the chambers to adapt the apparatus for use in narrow wells &c.
